Specification of Letters Patent.

Patented Dec. 25, 1917.

Application file'd July 5, 1913. Serial No. 777,475.

To all whom it may concern:

Be it known that I, RICHARD T. NEWTON, a citizen of the United States,and a resident of New York, in the county of New York and State of N. Yhave invented certain new and useful Improvements in Vehicles, of whichthe following is a specification.

This invention relates to vehicles provided uith shock absorbers oreliminators, and has in view the prevention or neutralization of shocksand vibrations when a wheel of a vehicle passes over a large body, butwhich also prevents or neutralizes the minor shocks that are caused whenthe wheels of a vehicle pass over minor objects, and to provide againstwhich is the special and main object of the pneumatic tires. Theinvention consists of a vehicle provided with casings containing sets ofcoiled springs and actuating parts all arranged as will now bedescribed, reference being had to the following specification and claimsand the drawing in which- Figure 1 is a side elevation of a portion of avehicle frame showing one form of the invention,

Fig. 2 1s a vertical sectional view on the line 22 of Fig. 1, and

Fig. 3 is a side view partly in section, of a slightly modified form ofthe socket plates.

Referring to the drawing there is shown a portion of a vehicle frame 10to which is attached an ordinary flat partly elliptic spring 11, securedby one end pivotally at 12, and resting on the beam 13 being part of therear axle not shown, of the vehicle. The other end of the fiat spring 11is rigidly attached to a ball 14, fitting in socket plates 15 which areadapted to slide freely in a cylindrical casing 16. The casing 16contains the coiled springs 17 and 17 the latter being the weaker of thesprings. These springs are actuated by the socket plates 15 as thecasing 16 or the ball 14 is moved in either direction. At the bottom ofthe cylinder 16 is the screw cap 18, and at the side is the slot 19through which the end of the flat spring 11 moves up and down. From theupper end of the casing 16, extend ears 20 through which passes thepivot 21. It will thus be seen that the casing 16 through the pivot 21and the ball 14 replaces the link or shackle which ordinarily connects aflat partly elliptic spring with the vehicle frame or an upper fiatspring. In Fig. 2 the ball is shown as passing through the socket plates15, whereas in Fig. 3 the socket plates are shown as imperforate withspherical cavities.

When a vehicle of this kind is used the effect of a shock is thecompression of the heavier spring 17, the lighter spring 17 alwaysfollowing so as not only to prevent clicking or noise, but moreparticularly to prevent shock and deterioration of the spring 17 as itreturns to its normal position. The coiled spring 17 is preferably soselected in regard to strength that it acts quickly and easily andtherefore materially assists the pneumatic tires of the vehicle andprolongs their lives. On account of the free suspension of the casing 16on the pivot 21, the casing is capable of assuming an inclined positionwhen the fiat spring 11 is more or less straightened out by a shock.This fact, however, does not militate against the correct reciprocationof the springs 17 and 17' because these work before any considerablelateral extension of the flat spring takes place. The ball and socketarrangement formed by the ball 14 and the socket plates 15 thereforeworks regularly and accurately.

The springs, 17 and 17 are always under tension, which may be regulatedby the screw cap 18, and they form contact with the socket plates 15 inperipheral recesses of said plates.

The above, description applying to one side of the vehicle is alsoapplicable to the otper side, both the sides being symmetri ca Variousmodifications of the device, involving the substitution of mechanicalequivalents may be made without departing from the spirit of theinvention. Thus the socket plates may be connected with the coiledsprings, or the coiled springs may be so formed at their interiorterminals that the socket plates may be entirely dispensed with.Likewise for the ears 20 and pivot 21 could be substituted a flexiblerod or other device to attain flexibility of connection.

What I claim as new is:

1. In a vehicle, the combination of a vehicle frame, a leaf spring atone end attached to the vehicle frame, an upright casing of a shockabsorber flexibly connected with the vehicle frame, coiled springs inthe casing, and a ball attached to the other terminal of the leaf springand located between and of the leaf spring and located between the 10adapted to actuate the coiled springs. socket plates.
